This is one of the earlier Quantums with no truss rod. It is in very good condition, with a few nicks and scuffs along the bass side of the neck (where you can't feel them while playing). The body is in excellent shape. The pickups have coil tap switches allowing for either single or dual coil operation.

I have a Q6 from 1990 and now a Q6 TBX from 1991 and I think that Modulus was making some of their finest necks during this time. They had a much flatter profile on the back which makes it easier for people like me with small hands to get around.
